What Is Blast-Frozen Fish?Updated 6 days ago

All Seatopia seafood is blast-frozen at peak freshness using commercial super-freezing technology. This is not the same as standard home or commercial freezing and the difference is significant.

How it works:

Super-freezing rapidly drops the fish to temperatures typically below -31°F / -35°C, locking in quality, flavor, texture, color, and the full-spectrum Omega-3 oils that make sashimi so prized. The speed of the freeze is what matters: standard freezing allows larger ice crystals to form inside fish cells, damaging texture. Super-freezing is fast enough that ice crystals remain microscopic, preserving cellular integrity completely.

What it delivers:

- Sashimi-grade texture and quality preserved at the moment of peak freshness

- Parasite elimination that meets FDA guidelines for seafood intended for raw consumption

- Shelf stability that allows ocean-freight shipping — reducing the environmental footprint of your order compared to air-freighted fresh fish

This process is what earns the "sushi-grade" or "sashimi-grade" designation — seafood frozen in a way that is both safe and exceptional to eat raw. It's also why a longer frozen date on the packaging is a quality indicator, not a warning sign.
